Application filed July 28, 1925, Serial No. 46,645. i Renewed March 23, 1928.

My invention relates to a support or socket for electrical devices in general and is particularly adapted for vacuum tubes of the three electrode type. which, when used in connection withV radio telegraphy and radio telephony, whether it be employed as an amplier, a modulator, an oscillator', a detector or for other purposes, and due to the elimination ,ofl the ferrule which surrounds the usual tube socket, eifectually eliminates dielectic losses and reduces absorptive losses to a minimum. One of they principal objects of my invention, therefore, resides in a very simple, inexpensive and highly effective low loss radio tube socket. The scope of my invention extends to whatever construction may be defined by or included within the terms or language of the appended claims. c

In the drawing:

Figure 1 is a side elevation illustrating my improved tube socket, showing a tube in position;

Figure 2 is al view in perspective of the.

socket member and Figure 3 is a transverse sectional view, on the line 3-3 of Figure 2 lookingv in the direction of the arrows.

My invention, in the form or embodiment shown in the drawing and brieiy described, comprises a base, 10, which I have illustrated as consisting of two sections, `11 and 12, which may be formed of Bakelite, rubber, glass, porcelain or similar insulating materials.

A plurality of suitably spaced socket members 13, which are preferably made of phosphor bronze, are carried by and adapted to pass through suitable openings, 14, located in the upper section, 12, of the base, 10. The tubular or socket members, 13, are each provided with an angular: extension, 15, which is threaded on its'outer lends as Y indicated at 16, for the purpose of receiving suitable lock nuts, 17. The vupper end of the tubular or socket members, 13, are provided with relatively narrow slots, 18, for the purpose of forming a perfect contact with respect to the usual lugs or leads, 19, of the tube, 20. The slots, 18, also permit the tube, 20, to be readily inserted in its proper position or its removal therefrom, without danger of distorting the socket members.l

It is to be understood, of course, that when my improved sockets are employedfor sub-panel mounting in radio receiving or transmitting sets, that I have found it desirable to provide the binding posts on thel bottom of the base, 10.

For the purpose of properly locating the tube, 20, with respect to the base, 10, and for the additional purpose of preventing its accidental displacement with` respect to the base, I provide a resilient member, 21, which is secured to the base, 10, by means of a screw or in' any other suitable manner. The upper end of the resilient member, 21, is curved slightly as at 22, in an outward direction, so that the tube may be readily guided into its proper position. An opening, 23 is provided in the resilient member, 21, near the upper end thereof for the purpose of aligning with the usual pin, 24, of the tube, 20. f

In order to readily locate the base,10, to the panel and 3to secure it thereon, I provide a pair of openings, 25.

Although I have illustrated the insulation base, 10, as consisting of the lower and upper sections, it is understood that I may readily cast or mold the entire base in one piece, and e'ectually support the tubular members,13, together with the terminals,

v15, and the .resilient member, 21, thereby providing a base that may be manufactured upon a high production basis.

I claim: l 1. A socket for vacuum tubes comprising a two-part insulating base and a plurality of terminal members connected therewith, each of said members comprising a splitsocket portion' extended through and projecting above one part of the insulating base and a solid portion arranged between the parts of the base vand projecting laterally beyond one wall ofthe base to provide cir-1 cuiting connectors wholly beyond ,the base, the projection of the socket portions above the base limiting the position of the connected tube to provide an air gap 'between the tube proper andthe base.

2. A socket for vacuum a two-part insulating base and a plurality of terminal members cn'nectedy therewith,

each of said members comprising a splitx socket portion extended through and projecting above one part of the insulating base and a solid portion arranged between the tubes comprising g 2 p p i 1,671,284

' parts. of the base and projecting. laterally carried .by and projecting above the ba'se to 4 beyondone wall oil the base to provide circooperate with a fixed part ofthe tube to cuiting connectors wholly beyond the base, secure the latter in place and indicate' its T0 the rojection of the socket portions above propercircuiting relative to the socket mem- 5 the ase limiting the .position of the con-r bers.
